Relating to the design-build method for certain government construction projects.

HB 4625 modifies Texas law to define when government entities must use the design-build method for certain construction projects. It applies to cities with over 100,000 residents, transit authorities under Chapter 451 of the Transportation Code, and other specified entities. The bill requires that design-build contracts cover only a single integrated project (like a linear transit route with multiple stops or a full water/wastewater system), prohibiting contracts for aggregated projects at multiple locations. This rule takes effect September 1, 2025.
